Abstract: ABSTRACT: "Echo canceller for a baseband data signal."      An echo canceller is used in a data transmission modem for cancelling in the baseband signal of the receive path an echo signal .epsilon.(t) produced by the data signal from the transmit path. The echo canceller comprises a difference circuit for forming the difference between the signal from the receive path s(t) + .epsilon.(t) and a synthetic echo copy signal ?(t). The echo copy signal is formed by at least one transversal filter which operates at a sampling frequency equal to the frequency of the data and whose coefficients are adjusted to minimize the mean-square value of an error signal.  This error signal e(n) at an actual sampling instant n or the filter is determined by forming the difference between the value of the output signal of the difference circuit at the instant n and the value of this signal at the preceding sampling instant (n - 1), previously multiplied by the ratio between the value of the data recovered at the instant n and the value of the data recovered at the instant (n - 1).

Abstract: ABSTRACT OF THE DISCLOSURE          A friction retard feeder adapted to feed sheets from a stack into a paper path located in a horizontal plane includes a tray which holds a stack of sheets at an angle of between 15° and 20° with respect to the paper path.  A paddle wheel having a plurality of blades is positioned a predetermined distance in front of sheets stacked in the tray so that as the paddle wheel is rotated the blades in a first position strike the top sheet in the stack in a plane parallel to the top of the stack and separates it from the remaining  sheets in the stack.  Continued rotation of the paddle wheel causes the blades to deflect downward in front of the stack and thereby inhibit movement of sheets other than the top sheet from the stack.  The tray also includes a high friction surfaced pad that cooperates with the paddle wheel in order to enhance the feeding of sheets near the bottom of the tray.

Abstract: Abstract of the Disclosure A microcomputer-based programmable control system for desiccant air dryers monitors the level of moisture saturation of the desiccant beds and adjusts the regeneration cycle accord-ingly to optimize energy efficiency.  The moisture sensors have capacitance probes and adjustable resistors as frequency deter-mining components for precision oscillators.  A multiple counter integrated circuit is controlled by the microcomputer to estab-lish a predetermined time interval and to count cycles of the precision oscillators during the predetermined time interval to obtain final counts for each probe indicative of the level of moisture saturation in the respective desiccant beds.  The microcomputer compares the final counts to a predetermined threshold number in order to determine whether a regeneration cycle is required, and also compares the final counts to max-imum and minimum threshold numbers to detect and indicate probe failure.  A pair of high and low pressure sensitive switches is provided for each desiccant bed, and the microcomputer tests for coincidence of the high switches and the low switches to monitor full depressurization and repressurization of the regenerating bed and to analyze and indicate valve malfunction.          The control system directly activates low current, low capacity solenoid valves which in turn operate high pressure pneumatic relays to drive the valves in the air dryer.

Abstract: ABSTRACT      A method for collecting from a surface area crude oil or a similar highly viscous, tough and tacky material which covers the surface area as a layer, is characte-rised by consecutively separating volumes of the layer by means of a curtain of a fluid which under pressure is driven into the layer and has been heated to a tempera-ture capable of lowering the high viscosity of the ma-terial in the volume, and applying suction to the mate-rial in the volume thus made low-viscous, for removing this volume of material from the area.    A suction nozzle for carrying out this method has a suction channel (1) which is connectible to a suc-tion conduit, a pressure fluid chamber (6) which has pressure fluid inlets and a first pressure fluid outlet (8, 9) surrounding the intake end of the suction channel.

Abstract: ABSTRACT OF THE DISCLOSURE    A cartridge for use with a revolver, automatic or submachine gun has a brass casing.  The interior of the casing has a substantially planar bottom wall extending radially from its flash hole.  A primer pocket in the base communicates through the flash hole with the casing interior within which the powder is ignited.  A parabolic curved section extends from the planar bottom wall to a sloped wall section.  The slope is in the range from substantially 5 to 15 degrees.  The casing wall thus narrows forwardly and terminates in an area of substantially uniform or constant thickness within which the bullet is frictionally retained.  With the parabolic curved section, the relocation of forces due to the discharging gases is substantially in a line which is parallel with the longitudinal axis of the cartridge.          The projectile velocity is thus substantially increased without subjecting the cartridge to undesired expansion, cracking or distortion.  This increases the firepower while eliminating the jamming problems occasionally incurred during the firing of automatic weapons.

Abstract: RIPPLE REDUCTION CIRCUIT FOR AN INVERTER                       Abstract A ripple reduction circuit for an inverter which converts DC power supplied on DC buses into AC power to drive a load includes a sensingtransformer having a primary winding coupled to one of the buses by a switch so that the ripple on the DC bus is sensed.  A periodic voltage is impressed across a secondary winding of the sensing trasnsformer due to the sensed ripple and this periodic waveform is coupled to a secondary winding of an output inductor.  A primary winding of the output inductor is connected between the output of the inverter and the load.  The primary winding of the output inductor receives a first ripplecomponent due to ripple on the DC bus and a second ripple component which opposes the first as a result of the periodic waveform in the secondary winding of the output inductor.  The two ripple components substantially cancel one another and hence a low distortion power waveform is delivered to the load.
